I totally lost the plot in the last few chapters, I guess the Mangaka knew the chop was coming a few issues ago.
Pity, it could have been really good if it had just taken it's time :/
I think Kei's gonna be in his Maid uniform.. so Yuuki can see the other peoples reactions.
I think he'd do it if it was to help his friends out.
then Yuuki has an excuse to join him so Kei "is not the only one"
